An Optimal Allocation Algorithm of Traveling Wave Grid Fault Locating Device

在研究行波定位装置的优化配置基础上,提出了一种用于配置行波定位装置后电网系统可观测性的判断方法,以保证电网系统所有支路可被检测为约束条件。以配置最少的行波定位装置和保证相同配置数目下配置方案具有最大量测冗余度为目标,构造了行波定位装置最优配置问题的数学模型,对于这个多目标优化问题,需要找寻一组全局最优解,应用二进制粒子群算法求解该问题可以得到满足条件的多种行波定位装置配置方案,对于多种可行方案引入冗余度指标进行优选从而得到最优的配置方案。最后,以某电网系统为例仿真验证该方法的可靠性。

Studied the method for determining the position- ing device configured traveling wave power system observabili- ty to ensure complete power system can be observed as con- straints. To configure the number of traveling wave positioning device to measure the amount of the minimum and ensure the maximum amount of measurement redundancy with the goal to establish the optimal traveling wave positioning device configu- ration issues mathematical model. This is a multi-objective opti- mization problem, the need to seek a global optimal solution, us- ing the improved binary particle swarm algorithm to solve the problem can be a variety to meet the conditions of the traveling wave positioning device configuration feasible solution. Finally, an example of a system to verify the reasonableness of the method.
